To all whom it may concern Be it known that I, ISAAC E. WARD, a citizen of the- United States, residing at Mount Hope, in the county of Sedgwick and State of Kansas, h. ve inventedcertain new and useful Improvements in Automatic Tiers for Hay-Presses; and I do hereby declare the following to be a full, clear, and. exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to automatic bale tying devices for hay-presses and can be attached to any rebounding hay-press and made to automatically act in conjunction with said press;

The invention-comprehends the construction and arrangements of parts to be herein? after. illustrated in the accompanying drawings, described in the specifications and succinctly defined in the appended claims.

In the drawings, Figure 1, is a perspective view of a part of a hay baler showing my automatic tier attached thereto. Fig. 2, a side elevation of the device with one of the side plates removed.

22 illustrates the coaptation- Similar numerals designate similar parts throughout the several views.

Referring to the drawings 1, designates a portion of a rebounding hay press mountedupon wheels 2, and a packer head 3, attached to the plunger beam 4. As I make no claim upon this part of a press, no explanation shown in Fig. 2) the central two fingers having cogs 56 and 57, the lower finger of said two has a downward incline 58, which will be referred to later. A spur-wheel 32 (Fig. 2) is made with internal cogs 35, and a rect'angular recess 60, Fig. 7, in the side of the rim in which is pivoted a dog 59, and a coiled spring 62, continuously keeps the edge pressed out. Said wheel is mounted upon an arbor 65, which-is journaled in the plates 7 and 8",(Fig. 3). In said plates are also journaled' arbors 30' and 30', see Fig. 3, which carry pinions 3434. On the ends of said; arbors outside of plate 8, are wiretwisters 64-64. Said twisters are of the form shown in Figs. 8-12 and 21. Fig. 12, is a vertical sectional view showin the cone shaped hub 71. of the twister wit in which is placed a spiral spring 72. The ends of said 'arbors are A portion of said shafts are splined which prevents the twister from turning thereon, the t-wisters being slidably mounted on said shafts so that when the nut 65, is turned any desired tension may be attained for the purpose of holding the wire between the said twister and the plate 8 (see Fig. A bracket 40, (Fig. 10) is made with 10m:- nal hearings in the central portion and is designed as a housing for a pair of bevel wheels 41 and 42. An inner extension 46' is 'made having a horizontal groove and the central portion is made withhemispherical threaded to receive nuts 6.

recess to receive a Vernal bearing 45, having a. square hole t erein to receive a square i The holes 46, are for tlie reception ofibolts or cap-screws-for a boxmg which hasa transverse-groove and a hemi sphe ieal recess, being similar to cap 26 hole therein ofa size to fit the shaft so that the shaft will rotate-said wheel and also slidebac'k and forth. In the end of the member 46 is a bore in which is jo'urnaled the end of. a shaft 50. Adjacent the end thereof is a bevel wheel 42, which engages bevel wheel. 41, and is affixed on said shaft with a key 43. A collar 44, is keyed'on the said shaft against the shaft bearing which serves to keep the wheels 41 and 42 in gear. Adriven wheel 49, is aflixed to'the said shaft 50, with a set screw 51. The bracket 40, is secured to the side bar 39, ofthebaler by means of screws 39 and a brace 4-8, ex-

tends therefrom to the baler and is secured thereto by bolts '55. The end of the shaft-13,

whoscbearing 45"1 haveglescribed, extends.

forward into the carriage as best seen in Figs. land 3, and has two pinions 30 and 31, thereon, 30 being between plates 6 and 7 and 31,'between plates 7 and 8. Inthe operation of my device it is necessary that this end of the shaft 13, move freely up and .down' and also continue to rotate with a minimum of friction, part of the time said 1 shaft is running idle and part of. the time it 'is engaged operating the. fingered cog rack, part of the time it imparts an intermittent rotative movement to the spur-wheel '32. And to this end special attention is given tothe construction as shown in F igs.-

2-5' 69 and 11. I will describe the bearing of the end of the shaft 13, as shown in Fig. 11, it being taken on the dotted line 103, of Fig. 22. The member 25, is made of the shape shown in Fig. 11, having a cap 26,

. with an opening 26,'through which said shaft passes and can play up and down. Between this capand the member 25, is a globular recess of a size to fit the ball which. has a square hole therethrough and allows/ the square shaft 13, to freely slide back and forth therethrough and when the member 25, is moved up and down the shaft is free. to move in any direction while rotating. Angle plates 15, (see Fig. 22) are affixed to plate 6, with rivets '14:, so as to allow the member 25, to slide up and down. The top end of 25, is substantially A shaped nd has a lateral lug 29, (see Fig. 11,) from whichextends vertically a spiral spring 27 the upper end of the spring bemg'aflixed in any 'suitablemanner as at 28. Openings 4:,

are made in the plates 6 and'7, of a size to allow the shaft l3, to freely move up and Referring to Fig. 9, I have provided two dogs 18 and 20, pivotally afiixed to the plate 6, with screws or rivets 19 and 23. Dog 20, is somewhat curved at its lower end and has a curved opening 21. A pin 22, in the plate 6, is located tolimit the movement of said dog. An arm extends laterally from the top of said dog to which is attached a spiral spring 24, the other end of the spring being affixed to a screw in plate 6.

Referring to Fig. 4, I have shown a vertical bar 37, having lateral bends (not shown) riveted to the plate 9. To said bar is at tached a plate 27 and to the free end there of is hinged a plate 16, and between this plate and the dog18, is a spiral. compression spring 17, see Fig. 22, and' when the dog 18, and 20, and the plate 16, are in a normal position they are as shown in Fig. 22. On

' the end. of, (see Fig. 15,) the finger bars 77 and '77, see Figs. 13 and 14 and dotted lines in Fig. 2, are hooks 78, approximately semicircular having notches 79 and 80 and a lateral pin 81. The ends of the finger bars are halved off as are the hooks and. are

riveted or bolted together shown at 5.

Riveted to the end of the. hook 78, is a wire cutter 83-, having a vertical edge and extending somewhat above the plane of the hook.

-Lugs 97 are secured to the baler and carry journals for-spools of wire 96. A pin 100 extends out of the baler around which the wire passes which serves to keep it in proper position. ,A spring 98, is attached to the baler with a screw 99, and when this screw is turned down it causes the spring to .press down on the wire and keeps the wire spool from over-running.

In conjunction with my bale tying device- I'use an improved bale block (Figs. 1617 and 18) made in three sections 86-87 and 88, preferably of sheet steel. Section 87, has horizontal apertures 96, said section is supported against outside pressure'by stay bolts 91. A vertical-bar 6 (Fig. 16) is given bends (not shown) and is riveted to the plates 95, which plates are bent and riveted to the plates 87. And to the bar 6 is riveted a lateral plate 90. Sections 86 and 88 are exactly alike so that the description of one will suffice for. both. Extenldlng pe endicular to the plane of the inner side o Pthe block section 86, are opposing studs 94, having a space between the ends. Onsaid studs are placed a strong spiral spring 92, the free' ends of which bear against bends of abrace 90, one end of which is afiixed with rivets 93, to the block section. The other endis pressed by spring 92 against the plate 7'.

:eo rs oaa Said plate is inform similar to plate 106, has lateral bend 108, said plates are placed inside the block section (best shown in Fig. 19) and secured thereto with the .7. same bolts as i'n'plate 106. The said b end is positioned in the openin s 96, below the i a block section 87. It is obvious thatwhen have constructed a movable carriage is that ill) I when the machine is in the act of tying and reaching for another wire the packer may be moving the carriage blocks and hay bale. Hence I have constructed a device that will operate on the move aswell as whenstanding still, and when the carria c has reached the limit of its movement- I lave provided means for automatically retnrning it home. This I accomplish by a rope 52, attached to the carriage and extending over a grooved piilley' '53 and aiweightlll', on the free endof'said rope.

Referring to ig. 8, it will be seen I have pivoted a bar 69, to the plate 8, and have attached thereto a spiral spring '68. A collar 66, has extending therefrom an arm 70, which engages the"pivot ed bar and holds it in a normal position, sa d collar being adj ta e i e by a s cr w 67, o th spurwheel shaft 65.

Having descr bed the construction and assembling of my device I will now describe its modes ope Mada To describe the tying of one wire will suliice as both wires are manipulated the same.

hen it is desired to operate the machine, the wire is taken oif the spoo l'and' placed under the pin 81, (Fig. and in the notch 79, and the finger 77, pushed back until the free end Of the wire is held by friction between'the hook and, the knife 82, see Figs. 13 and 15. It is to be observed the shaft 13, is continually rotating and the pinion and 31, are running idle and when the packer pushes the hay back against the wire 85, it will be as shown in Fig. 15 The pressure of the ha 'v having pressed against the hinged plate 16, will through the medium of the spring 17, push'the pivoted dog'lS, against the dog 20, and off the member 25,, at which time the spring 27, will draw the member 25, up against dog 18, which is the r in the position asindicated by the dotted lines'in Fig. 22, raising the pinionifl, into an intermediate position asshow'n at Fig. 5,. The bale block (Fig. 16), is then'se't in with the plate 90', adjacent the hinged plate 1.6, and w en th a 1 Pa er prs e the ble k 's 90'' that l fgil d Pl it 15, 91 9 later l y into the hollow df the b1o ck 87,and the spring 17 will throw the plate 16, and the dog/118, back to their normal position as shown in 9, and the sprin'g 27yiyill" raise the member 25, bet-ween the dogs 18 and 20, (see Fig, 9) bringingthe pinihn's 30 and 31 up into the tep position as shbwn in Fig, 2, which engage the. cogs 3C), and 57 and thereby impart an intermittent rotati-ve movement to thewheel 32,0oii1cident therewith said wheel also intermittently rotates the pinion 34, and tlirough the medium of the shaft 30, causes the wire t wister 64, to take hold of said wire as shown at Fig, 2,21 slight movement of the finger having released the end of the wire, and it is tal ten up as indicated, the rod 38, keeps the wire against the bale. Simultaneously with the movement of the twister 64, the intermittent movement of the wheel 32, causes thearm'IO,

to release the pivoted bar 69, whiel dropsdown Into the hollow S7" of the bale block andthe carriage and the bale block move on.

together. The bale block 87, being in the position shown at Fig. 13, the pinion having become engaged with the cogs 57' ig'. the finger 77, is rim across the baler as shown at Figs. 13 and 14, said pinion having followed the cogs around the bars and when engaged with cogs 56, runs the rack back home and takes the Wire back with it, the Wire havin been caught in the notches 79, and 80, o the hook 178. The wire is then in the position as shown in Fig. 1 3 The members Fi 19, being laterally inclined cause the wire to pass down under the end ofthe plate '7' and into'ft e posit-ion at 112 It is to be specially 0 served that at the instant the cog rack lands at home the incline 58 (see Fig. 6) contacts the pivoted, dog 59 (it having passed throu h the opening 101, Fig. 20, in the plate and starts the wheel 32,' and thereby brings the co s 35, in contactwith the pinion 31, and the end oi the twister takes hold of" the wire and pulls it back in the notch 75, in the plate 8 The wheel continuing to ro-J tate and through the medium of'the pinion 34:, twists the ends of the wire together as shown at Eiggzl, meantnne while the twister was putting the wire taut the knife 82, was making ablen d 8ft. the wire after which it cutit 'ofi and the free end of the wire remained held between the knife and the hook. Moreover dnringthe process oi; twisting the ends of the balin gwire the revolution of the Wheel 32, brought the arm 70, around in its rotation andlifted the pivoted bar 69, out

of the balblock, therebyseparating the caragfifand block and the Weighted rope .52, returned the carriage'frbm its recejht-position' as indicated by'the dotted lines (i4 to its normal position as shown at Fig. l. The hay; plunger again be ins to move 'th lock and bale'of hay'p'ae' ing more ha agailist the block. When the halo block passes out of the baler the wire will come out of the block by passing down beside the plate 106.
